Glad to help!Here is the obituary:
Times-Picayune, June 11, 1948:
WILLIAMS - At Baptist hospital on Thursday, June 10, 1948 at 5:03 o'clock a.m., ARTHUR J. WILLIAMS, SR., of 130 Royal street; husband of Emma Pilote; father of Arthur J. Williams, Jr., Mrs. John A. Turcich, Jr. (former Marguerite Williams); grandfather of Diane and Marguerite Turcich; cousin of Arthur Baker of Mobile, Ala., aged 58 years, a native of Macedonia, Greece, and a resident of New Orleans for the past 44 years.
Relatives and friends, also officers and members of the Greek Society are invited to attend the funeral, which will take place on Friday, June 11, 1948, at 3:45 o'clock p.m., from the funeral home of Lamana-Panno-Fallo, Inc., 625 North Rampart street, near Municipal Auditorium.Religious services at Greek Hellenic Orthodox church, 1222 North Dorgenois.
Interment [ill.] Metairie cemetery.
So, it stands to reason that Arthur/Athas is probably also from Macedonia.Of course, what used to be Macedonia, Greece, was divided into Greece, Serbia, Bulgaria, and Albania.So, you definitely have your work cut out for you! :-)
As a former resident of New Orleans, I can tell you that the Greek community puts on this really great festival every year - with AMAZING food - and I am including a link to their contact page.Somebody there might be able to tell you what became of the old records of the Greek Society mentioned in the Williams obituary.Because 10-to-1 odds are that Athas/Arthur was a member, too, and sometimes these societies had very detailed records about their members.It's worth a shot, anyway, and hopefully somebody with the Greek Festival can put you in touch with somebody from the Society.
Hope this helps!Wishing you the best of luck with your search!
